HANDLE OF CYCLES.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed March 14, 1908. Serial No. 421,213.

To all whom it may concern:

Be it known that I, VALTER CARDIFF MEAD, a subject of the King of GreatBritain and Ireland, residing at High street, Maldon, in the State ofVictoria, Commonwealth of Australia, have invented certain new anduseful Improvements in the Handles of Cycles, of which the following isa specification.

This invention relates to an improved adjustable handle bar for cyclesand which is so constructed that the position of the handles may beadjusted radially to the desired height most convenient to the rider.The handle bar according to this invention is preferably constructed ofa straight tube, made in one length, and supported above the ordinaryhandle bar pillar by tubular posts which spring from a shorterlongitudinal tube which is supported by another tube secured to the topportion of said handle bar pillar and capable of being oscillatedtherein. Said handle bar is locked at the desired height or position bymeans of a screwed friction clutch of novel con struction having one endfurnished with a handle or hand wheel, also the handle bar is furnishedat both ends with a novel con struction of grip handle.

The invention will now be fully described aided by a reference to theaccompanying sheet of drawings in which Figure l is a front view andFig. 2 a side view of my improved adjustable handle bar as fitted to anordinary handle bar pillar. Fig. 3 is a central longitudinal sectionshowing the friction clutch locking appliance and Fig. 4 a verticalsection on line 1-1 Fig. 3.

In constructing my invention the handle bar proper is formed of astraight tubular bar A rigidly connected on each side of its center toone end of a tubular post A the other ends of which are rigidlyconnected to a tube A which passes through the T piece B of the handlebar pillar B while about the outer surface of the tube A is a tube Awhich is cut into either two, three, or four sections and each sectionhas a projecting stud a which passes through a hole a formed in the tubeA Inside the inner tube A is a rod C which is screw-threaded at one endto take into a nipple C secured to the inner tube A which has secured onit outside collars a which prevent the latis furnished with a cone pieceG which is designed to bear against the studs a and force them outwardswhen the rod C is screwed in the proper direction by the hand wheel Oand thus cause the divided tube A to bear hard against the insidesurface of the horizontal barrel of the T piece B of handle bar pillar BBy turning the hand wheel C in the opposite direction the cone piece Cis withdrawn from under the studs 64 and allows the handle bar A freedomto be adjusted to any position to suit Elie rider, as shown by thedotted lines in Each end of the handle barAis furnished with aperforated tubular grip pieceD which is of a slightly larger diameterthan said handle bar A and is secured thereon by means of a reducingnipple D which is suitably secured in the end of said grip piece D andthe reduced portion of said nipple D screwed into a nipple D secured inthe end of the handle bar A. Said grip piece D is provided with a numberof perforations d while the handle bar A is also perforated at (Z toallow a current of air to pass through the said handle grip D to keepsame cool. If desired the handle grip D may be covered with leather orthe like for warmth in winter.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is 1. An adjustable handle bar for cyclescomprising a handle bar pillar having a hollow cross head, a handle bar,a tube parallel therewith and passing through said head and adapted toturn therein, rigid radial connections between said tube and said bar,and manually operative clutch mechanism within said head for lockingsaid tube therein against turning and whereby said tube can be releasedto permit adjustment of the handle bar around said head as a center,substantially as described.

2. An adjustable handle bar for cycles comprising a transverse tubularportion, a member passing therethrough and adapted to turn therein, ahandle bar spaced a distance from said member and having rigid radialconnection therewith, whereby as said member turns in said tubularportion said handle bar swings from the same as a center, and clutchmechanism arranged in said tubular portion for locking said membertherein against turning, said mechanism having an exterior operatinghandle arranged adjacent an end of said member.

3. An adjustable handle bar for cycles comprising a tubular portionadapted to be fixed to a cycle frame, a handle bar, a tubular memberassing through and adapted to turn in said portion, a longitudinallyadjustable cone in said member provided with means whereby the same canbe adjusted from the exterior of said member, and an expanding clutchmechanism within said portion and adapted to be expanded by said cone tolock said member to said portion against turning therein.

4. An adjustable handle bar for cycles comprising a tubular portionadapted to be secured to a cycle frame, a handle bar provided with ahollow member extending into and adapted to turn in said portion as thehandle bar is adjusted, an expanding clutch within said tubular portionand at the exterior of saidmember and provided with portions projectininto said member, and a cone within sai member provided with exterioroperating means and adapted to engage said portions and expand suchclutch to lock said member to said tubular portion, substantially asdescribed.

5. An adjustable handle bar for cycles comprising a tubular portionadapted to be and means within said member for engaging said studs andexpanding said clutch to lock the member and portion together.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

WALTER CARDIFF MEAD.
